Blank every Recollection which contains another non-blank Recollection as a substring.

Replace the first paragraph of “Recollections” with:-

Each Memory of Atlantis has a Recollection, being a string of publicly-tracked flavour text, which if not blank should describe (or hint at) a description of the fate of Atlantis and how the next dynasty of BlogNomic will revisit its fall.

Add to “Recollections”:-

A Memory of Atlantis may never change their Recollection to a string which contains the entirety of another Memory of Atlantis’s non-blank Recollection as a substring.

If a Memory of Atlantis’s Recollection is a shorter substring of another Memory of Atlantis’s Recollection, and is not blank, then the former Memory of Atlantis is said to Concur with the latter. In addition, a Memory of Atlantis always Concurs with itself.

If “Compound recollection” enacted, add the following to “Primary Source”:-

A Memory of Atlantis may change their own Recollection to be a shorter substring of another Memory of Atlantis’s Recollection, at any time.

Readding the change-Recollection-to-a-name mechanic should Compound Recollection (inadvertently) remove it, and also changing it from names to a more mechanical and thematic substring system: if you want to support a Recollection of “Atlantis was consumed by fire one terrible night”, you can change your Recollection to “consumed by fire” or “terrible night” or anything else that’s in there.
